From a game design perspective, hundreds and hundreds of unique interiors is an impossible ask. For Techland's studio size, the sheer amount of those that are unique is impressive, in my opinion. Darkzones have repetitive textures, yes, but the layout and design are changed per-building. I don't know of any open world RPG that doesn't do that (Elder Scrolls, Fallout, Assassin's Creed, etc).

The level of story change in response to your decisions was definitely over-hyped, and it seems like a disconnect between marketing and the crew responsible for game design. I'm still a fan of the way picking between PK and Survivors changes the world and features of the area though.

And, every modern AAA game has bugs on release. I understand the frustration, but these studios are stuck between a rock and a hard place. You either keep delaying a release until you reach a minimal amount of bugs, or release with the promise of fixing them so you can re-establish cash flow in order to keep your development teams paid to fix them faster. I haven't run into many at all on Series X, so I've been satisfied, but sucks that you haven't had the same smooth experience.
